A genome-wide CRISPR screen in Anopheles mosquito cells identifies fitness and immune cell function-related genes Nature Communications - Mosquitoes are major vectors for the transmission of many serious pathogens. This study uses genome-wide CRISPR screens in the mosquito, Anopheles gambiae, to reveal new...

Pleased to share our recent work in collaboration with the
@perrimonlab.bsky.social in which we perform the first genome-wide CRISPR knockout screen in Anopheles to examine essential fitness genes and genes associated with clodronate liposome function

Sarah Merkling wants to "pasteurize" mosquitoes! At the Institut Pasteur, Sarah Merkling's research focuses on a topic that is still largely unknown: interactions between mosquitoes and viruses. She boldly devises novel strategies based on state-of-...

🦟 Can we "pasteurize" mosquitoes to stop dengue & Zika?

Sarah Merkling @merklinglab.bsky.social uses AI + CRISPR to analyze stomach cells and understand why some mosquitoes spread viruses while others don't.

Goal: Make disease-carrying mosquitoes harmless.

Excited to announce the final version of the Mosquito Cell Atlas is out now in @cellpress.bsky.social!! 🦟🩸

There is SO much left to find & investigate in this dataset (& the rich biology of the Aedes aegypti mosquito)! We hope this helps scientists in many fields!

It was about time to leave the old platform and join this one!
Excited to connect with old and new friends here 🧬✨

Infectious bacteria, but not the microbiota, induce a NOX-ATM-cytokine pathway that controls epithelial turnover Nagy et al. identify a NOX-ATM-cytokine signaling axis in the Drosophila gut that is activated by infection independently of DNA damage. This pathway promotes enterocyte loss, cytokine production, and...

Our new study is out in Cell Reports!
We show that the DNA repair pathway ATM-Ξ³H2Av is repurposed in the gut during infection, even without DNA breaks. Pathogens, not microbiota, trigger it via NOX to clear damaged cells and drive stem cell regeneration. www.cell.com/cell-reports...
